Create the baseline Makefile, platform definitions file and platform specific assembly macros file. This includes first set of constants for the platform including cache sizes and linker format and a stub for BL31 and the basic memory layout K3 SoC family of processors do not use require a BL1 or BL2 binary, since such functions are provided by an system controller on the SoC. This lowers the burden of ATF to purely managing the local ARM cores themselves. Signed-off-by: Benjamin Fair <b-fair@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Andrew F.

Trusted Firmware-A for Texas Instruments K3 SoCs
|
|
================================================
|
|
|
|
Trusted Firmware-A (TF-A) implements the EL3 firmware layer for Texas Instruments K3 SoCs.
|
|
|
|
Boot Flow
|
|
---------
|
|
|
|
R5(U-Boot) --> TF-A BL31 --> BL32(OP-TEE) --> TF-A BL31 --> BL33(U-Boot) --> Linux
|
|
\
|
|
Optional direct to Linux boot
|
|
\
|
|
--> BL33(Linux)
|
|
|
|
Texas Instruments K3 SoCs contain an R5 processor used as the boot master, it
|
|
loads the needed images for A53 startup, because of this we do not need BL1 or
|
|
BL2 TF-A stages.
